The short answer
The best generative engine optimization (GEO) tools for SaaS companies cover four jobs: an AI readiness scanner to make sure crawlers can read your site, an AI visibility tracker to see whether ChatGPT, Perplexity and Google AI Overviews recommend you, server-side crawler tracking to see which AI bots visit, and a content workflow that turns lost questions into pages. A small SaaS team can cover the first three with LLM Scan from $19 per month, or combine a tracker such as Otterly.AI or Peec AI with free checks; larger teams look at Profound, AthenaHQ or the AI features of Semrush and Ahrefs.
We make LLM Scan. Competitor prices below come only from each vendor's pricing page on 7 October 2026; for the rest, check their pricing page.
Why GEO matters for SaaS
SaaS buyers increasingly ask assistants questions such as "best [category] for a 20-person team" or "[your product] vs [competitor]" before they visit a website. If the answer lists three competitors and not you, you lose the deal without seeing it in analytics. GEO is the work of being readable, citable and named in those answers.
The SaaS GEO stack
| Job | What it answers | Example tools | Cost to start |
|---|---|---|---|
| AI readiness scan | Can AI crawlers read my site? | LLM Scan free scan, llms.txt checkers, Google's Rich Results Test | Free |
| AI visibility tracking | Do assistants name and cite us for buyer questions? | LLM Scan, Otterly.AI, Peec AI, Profound, AthenaHQ | From $19/month (LLM Scan), €29 (Otterly.AI), €85 (Peec AI); others: check their pricing page |
| Suite add-ons | How does AI visibility compare with my SEO data? | Semrush AI toolkit, Ahrefs Brand Radar | Check their pricing page |
| Crawler analytics | Which AI bots visit, and which pages? | Server logs, LLM Scan crawler tracking | Free with your logs |
| Content workflow | What should we publish or fix next? | Weekly fix lists, content briefs, your CMS | Varies |
1. AI readiness scanner
Start here because it is free and fixes are quick. Check robots.txt rules for each AI crawler, llms.txt, sitemap, structured data and whether your key copy is in the raw HTML. SaaS sites often fail on the last one: pricing tables and feature grids rendered only with JavaScript. LLM Scan's free scanner checks 8 areas and gives ready-to-paste fixes; see how to check whether your website is ready for LLMs.
2. AI visibility tracker
This is the core GEO tool. It asks assistants the questions your buyers ask on a schedule and records mentions, position, cited sources and competitors. For SaaS, track three kinds of prompts: category ("best [category] for [use case]"), comparison ("[you] vs [competitor]") and brand ("what does [you] do, and how much does it cost?"). Comparison prompts are where SaaS brands win or lose most often.
- LLM Scan: weekly report with AI answers next to Google rank and AI Overview citations for your keywords, plus 3 fixes. Starter $19 (1 domain, 20 prompts, 1 assistant), PRO $59 (3 domains, 40 prompts, ChatGPT and Perplexity).
- Otterly.AI: daily tracking; Lite €29 for 15 prompts on 4 engines.
- Peec AI: daily tracking and analytics; Starter €85 for 50 prompts and 3 models.
- Profound and AthenaHQ: platforms aimed at larger programs; check their sites.

3. Crawler analytics
AI crawlers do not run JavaScript, so your product analytics never sees them. Read your server logs, or report crawler visits from your server. LLM Scan's crawler tracking gives each monitored domain a token and snippets for Next.js, Cloudflare Workers and plain HTTP, and recognizes bots such as GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, PerplexityBot and Bingbot. If you see your docs crawled but never cited, the problem is content, not access.
4. Content workflow
Tracking is only useful if it changes what you publish. SaaS gaps usually map to a few page types: a comparison page per main competitor, a clear pricing page in HTML, use-case pages for each audience, and docs that answer setup questions. LLM Scan's weekly report ends with 3 fixes; PRO and Agency add Content Machine briefs based on AI search demand and citation gaps. See turn AI visibility gaps into a content plan.
What we would buy at each stage
- Pre-launch or early: the free scan, plus manual checks of 10 buyer questions in ChatGPT and Perplexity each month.
- Seed to Series A: a self-serve tracker on 20 to 50 prompts. LLM Scan Starter or PRO if you want Google and AI in one weekly report; Otterly.AI or Peec AI if you need daily data on more engines.
- Growth stage with a content team: more prompts, more engines and a content workflow; compare Peec AI, Profound, AthenaHQ and LLM Scan Enterprise.
- Developer tools: also check that your docs are crawlable and that llms.txt points to them. See AI visibility for developer tools.
